UNITED STATES EMIL F. BITTER, OF SOMERVILLE, NEW JERSEY.

TOILET SEAT.

Application filed August 24, 1921.

To all whom it may concern:

Be it known that I, EMTL F. BITTER, a citizen of the United States, and a resident of Somerville, in the county of Somerset and State of New Jersey, have invented a new and Improved Toilet Seat, of which the following is a full, clear, and exact description.

This invention relates to improvements in toilet seats, particularly to an attachment for a seat which is primarily intended for use wit-h chemical toilets and other forms of commodes.

An object of the invention is to provide means associated with the seat for normally concealing the contents of the bowl and to provide means whereby a weight on the seat moves the concealing means to inoperative position.

A further object is to provide a device of this character for toilet seats, which will be simple and practical in construction, efficient in use, easy to clean, unlikely to get out of order and comparatively inexpensive to manufacture.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a top plan view of my improved toilet seat, showing the shutter in closed position;

Figure 2 is a view in transverse section on the line 2-2 of Figure 1;

Figure 3 is a similar View on the line 33 of Figure 1, showing the shutter in open position; and

Figure 4 is a fragmentary bottom plan view of the seat.

Referring in detail to the drawings, I have illustrated a conventional form of chemical toilet which includes a bowl 1, brackets 2 projecting rearwardly from the bowl and a seat 3 hingedly connected at its rear end to the brackets. A lid 4 is hingedly connected to the seat 3, as indicated at 5.

Arcuate ribs or flanges 6 carried by the under face of the seat 3 guide the swinging movement of the seat and fit snugly within the sides of the bowl 1. Curved plates 7 fixed to the under face of the seat at opposite sides of the usual opening 8, extend inwardly and downwardly into the bowl.

Serial No. 494,847.

The adjacent edges of the plates 7 are parallel, as seen most clearly in Figure 1.

A pair of crank shafts 9 extending longitudinally of the seat 3 are mounted in suitable brackets 10. The crank shafts 9 carry arcuate plates 11 adapted to close the opening between the plates 7 and conceal the contents of the bowl. The tw plates 11 act as a shutter and swing laterally whenever n'essure is exerted on the seat 3. The crank shafts 9 are of course mounted in such a manner that the plates 11 swing clear of the plates 7.

The swinging movement of the plates is 7 accomplished by a pair of crank arms 12, integral with the shafts 9. A flat spring 13 having its intermediate portion secured to the under face of the forward end of the seat, as indicated at 14, is operatively connected at its ends to the crank arms 12, nor mally exerting sufficient pressure on these crank arms, to retain the shutter in closed position.

When a weight is deposited on the seat 3, 89

open. lVhen the weight is removed from the seat, the spring 13 will operate the crank arms to close the shutter and raise the seat, as will be readily understood.

It will be seen that I have provided means for overcoming the principal disadvantage 90 and objection of chemical toilets, and although I have illustrated one of the preferred embodiments of my invention, it will be apparent that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention and hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such sight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. The combination with a toilet seat having an opening therein, and a bowl, of crank shafts mounted on the under face of the seat, plates carried by the crank shafts cooperating to form a shutter, crank arms on the shafts. a spring acting on the crank arms to normally hold the shutter in closed position, said crank arms engageable with the bowl upon depression of the seat to open the shutter against the action of the springs.

2. The combination with a toilet seat having an opening therein and a bowl, of brackets fixed to the under face of the seat, crank shafts jonrnaled in the brackets and extending under the opening, plates carried by the crank shafts cooperating to form a shutter, crank arms on the shafts, and means acting on the crank arms to normally hold the shutter in closed position, said crank arms being engageable with the bowl upon depression of the seat to separate said plates. I

The combination with a toilet seat hav- EMIL F. BITTER.
